IMPROVEMENT |N FAUCETS AND vENTs.

I Specification forming part of Letters Patent No. 40,044, datedSeptember 22, 1863.

T0 all whom it may concern,.-

Beit known that I, J AcoB J'AnBAUs, ofthe city of Buffalo, and State ofNew York, have invented a new and Improved Beer-Faucet; and I do herebydeclare that the following is a full and exact description thereof,reference being made to the accompanying drawings, making a part of thisspeciiication, in which Figure I is a section of my improved faucet.Fig. II represents the Ventilating-plug as standing in the top ofbeer-barrel with a cord leading to the faucet. Fig. III is a transversesection of the discharge-nozzle.

The nature of this invention relates to the construction and arrangementof a compound discharge-nozzle, which will freely discharge the liquorthrough its outer cylinder, when the valves are raised, and which allowsa quantity of liquor to remain in the inner cylinder to be forced outthrough a small aperture in its bottom in the act of closing the valves.

Letters of like name and kind refer to like parts in each of thefigures.

A represents the main body or barrel of the faucet through which theliquor is drawn.

B is a valve-cylinder, which is screwed into the bulb a', (orlargeprojecting end of the faucet.) It projects upwardly and at right anglesthereto, or nearly so.

C is a valve-stem, and C and O2 conical valves connected therewith. Thevalve-stem Works through a stuffing-box, D. Conical valve-seats are madein the bulb, into which the valves tightly iit when closed.

E is a lever, acting upon the valvestem, for opening and closing thevalves.

F is a post projecting upwardly from the main body of the faucet for thesupport of the' lever. It has a pin or fulcrum shaft in the top, asshown at f', upon which the lever works.

The discharging-nozzle has two cylinders, G and H. These two cylindersare connected together at the top and screw into the under side of thebulb, as shown at I. The outer cylinder, G, is open at the bottom. Theinner cylinder, H, is made much smaller than the outer, so as to leaveample room for the liquor to pass between the cylinders and out at thebottom of the outer cylinder. The inner cylinder is made flaring at itsupper end, so as to form a tight connection with the outer at sitextreme upper end.

flaring part of the inner cylinder to allow the beer or liquor to flowthrough into the outer cylinder.

A stationary head, h2, is put into the lowerend of this inner cylinder,through which head there is a very small hole, as shown at j. M

K is a hollow piston-rod, which screws into the lower end of thevalve-stem C, as shown in the drawings, and projects downwardly so as toact as a forcing-piston in the cylindrical part of the inner cylinder.Small holes K are made through this hollow piston-rod to allow theliquor to flow through and down into the cylindrical chamber below atsuch times when the piston-head may stand partly below the holes h.

A puppet-valve, L, is connected with this piston-rod. It has a longvalve-rod, n, Which passes up through the piston-rod, and has a largehead, n', on the top. The red lines show the valves and piston, 85o., intheir lowest position, the valves being closed and the iow of the liquorshut off.

M represents a ventilating-plug, which is inserted into the upper headof the barrel containing the liquor. A smaller plug, M', is projected atright angles therefrom, with an aperture, O, which opens into theexternal air. A conical valve, P, works on. the outside of this smallplug.

Q is a spiral spring, which is placed on the plug in order to force thevalve back to its place, as represented by the red lines Pf, when thefaucet is shut.

R is a string or cord which connects this valve with the end of thelever E.

S is a section of the cask which contains the beer or other liquor.

Operation: The faucet is inserted into a barrel or cask, containing theliquor to be drawn, in a common manner. The red lines in Figs. I and IIshow the valves all closed and the flow of the liquor shut off. Now,lift on the handle of the lever E and raise the valves c c2 but slightlyand the liquor will flow through the faucet, passing through the holes hinto the outer cylinder, G, and thence into the glass. If the lever israised high enough to bring the head of the piston K above the holes h',then the liquor will quickly fill the inner cylinder, H, below the holesh', and pass through the holes h into the cylinder G, and thence intothe glass or vessel into which it is to be drawn. When thelever E ispressed down, Eo as to close the valves, the piston K is also forceddown at the salne time into the inner cylinder, H, and thereby forcesthe liquor, which had collected therein, through the small aperture jinto the liquor already in the glass, thereby producing a livelysparkling foam on the surface and imparting life and sharpness to thebody of'the liquor in the glass. 1f the lever is not raised high enoughto raise the piston-head above the holes h', which will be the case whenyou desire to draw the liquor very slow, then sufficient liquor willpass through the holes K to fill the cylinder H be- 10W the piston, sothat when the pistou descends it Will fol ee ont, through the small holej, what liquor there had collected in the cylinder, and produce the sameeffect as before stated. When the lever is raised so as to open thevalves c c2, it will pull n pon the string 1i sufficient to inove thevalve P back far enough to open the vent. When the lever is pressed downso as to shut the valves, it loosens the string sufficiently to allowthe spring Q, to force the valve P back to its place in a manner toclose the vent.r y

I claim as myinvention l. The compound discharge-nozzle composed of thecylinders G and H. in combination with the hollow valvepiston K, (withor Without the holes K,) Valve-stem C, and valve c ,02, and lever E,arranged and operating for the purposes and substantially as described.

2. The valve P, arranged and operating upon the outside of theventilating-plug M', substantially as set forth.
